What does your textbook say about OPTICS?
Optics . Different coloured light has different wavelength and frequency. . Among the visible light, violet light has the lowest wavelength and red light has the highest wavelength. . When light is incident on the interface between two media, it is partly reflected and partly refracted. . REFRACTION OF LIGHT When a ray of light travels from one transparent medium into another obliquely, the path of the light undergoes deviation. This deviation of ray of light is called refraction. Refraction takes place due to the difference in the velocity of light in different media. The velocity of light is more in a rarer medium and less in a denser medium.

Optics . Different coloured light has different wavelength and frequency. . Among the visible light, violet light has the lowest wavelength and red light has the highest wavelength.
. When light is incident on the interface between two media, it is partly reflected and partly refracted. . REFRACTION OF LIGHT When a ray of light travels from one transparent medium into another obliquely, the path of the light undergoes deviation.
This deviation of ray of light is called refraction. Refraction takes place due to the difference in the velocity of light in different media. The velocity of light is more in a rarer medium and less in a denser medium. Refraction of light obeys two laws of refraction.
